Weer213 1- Bring up the console command with the button " ` " without the ""
and type the following command:
cg_fovscale and add your value for example 1.4
cg_fovscale 1.4 and it will apply the new field of view
i would say to not go any higher of 1.6+ as it causes problems with the screen... but your free to do as you like. That is the command to change the field of view my friend!
And make sure in settings you set the field of view to 65!

Nawa no man, anti aliasing didn't fix it it turned out to be the depth of field... everyone has is... and unfortunately you cannot turn it off only set it to "low" and even at low half of your screen is blurry when aiming... but eh i found a command and i removed the depth of field so now i dont have anything blurry anymore.
